摘要
将粒子群算法应用于飞行控制系统的优化设计中,需要解决两个问题:如何选择目标函数和如何确定初始种群和算法运行参数。针对这两个问题,分别提出了基于参考模型的飞行控制系统优化策略和基于均匀设计的粒子群算法初始种群和运行参数的选择方法。仿真结果表明,本文所提出的优化策略能够有效地解决飞行控制系统的优化设计问题,粒子群初始种群分布均匀,收敛速度快。
Two problems need to be solved： how to select the object function and how to determine the initial swarm and parameters of the particles swarm optimization （PSO）, when PSO is applied in the optimization of flight control systems. Concerning these problems, an optimizing strategy based on reference model for the flight control system （FCS）, and a method based on the uniform design to select the initial swarm and parameters of PSO were given. The simulation shows that the optimizing strategy can solve the optimal design of the FCS effectively, the initial swarm got by the selecting method distributes uniformly, and the PSO with these initial swarms has more rapid convergence velocity.
